Question

shed roofing questions


1. when hanging 1/2" plywood or OSB sheathing on the roof of a shed, can i use framing nails 2-3/8" with my nailer or do i have to use roofing nails manually. i have hot-dipped galvanized ring shank 2-3/8" nails for my nailer.

2. what is the sequence of materials i need to apply on top of the sheathing (tar and shingle) and what fasteners should i use? are roofing nails used for these outer tiers while framing nails are OK for the sheathing (just guessing)?

the shed is pretty small, 11x9"

thanks

framing nails ae over kill for sheeting.. you can use a 2" nail or I like to use screws.. for the roof sheeting I like to use flooring screws. once the roof is done, you can put tar paper (stapled down), then asphalt shingles (using roofing nails).

i have smaller nails for my gun, 2-3/8". nails are cheap, time is expensive. screwing or manually nailing would take a hell of a lot more time.

thanks

Just use 2" or 2-3/8" nails ,that's what i USE and that is what you are suppose to use.
As far as the sheathing goes don't forget to stagger sheets and throw some 7/16" plywood clips in between.
Next is felt ,either 15# or 30# use staples for that..
Once you get your felt down trim around and install a drip edge.
In addition you will need some vents and if required (don't know your location ) you can put down some ice and water shield as well (before felt).

Question

shed roofing questions


as far as the spacing goes, for the sides (walls), i was spacing by eye about 1/4". i hope that should do.

vents? i have one 3" PVC vent stack going through the roof for drain plumbing, are you referring to some other kind?

also, any tips of trimming the roof would be appreciated. i am putting aluminum (i think) stock coil flashing on the fascia and soffit but was thinking what to do with the edges of the OSB board, i.e. where the shingles meet the OSB. ideas?

thanks

You will need couple soffit vents and couple "mushroom" vents for air circulation.
Drip edge is to finish of OSB edges and to cover top of the fascia coil.
What is the size of your fascia ?
There is 2-1/2 drip edge and 1-1/2 , you fascia coil cant be lower than 2" from the top.

Question

shed roofing questions


the fascia is about 4" high and 10" wide (or deep however you look at it, i.e. 10" from the edge of the roof to the wall of the shed).

which products do you recommend for the soffit and mushroom vents?

thanks

Use one of your sheathing nails as a gauge for end spacing, and the clips as a gauge for edge spacing. The edges of your sheathing should be protected with drip edge. I believe that SteelToes was referring to soffit and roof or ridge vents, as opposed to your waste vent. What is the purpose of the waste vent in your shed?

i have water in the shed, believe it or not, and a mop sink. i am involved in various outdoor sports and my stinky and muddy gear needs to be washed after every time and if i do it inside the house, it stinks. one of the reasons for building the shed.

Actually, the nails he has are exactly what he needs. 2 inch nails would not meet code (if that's an issue here) for roof panels. Also, it's "sheathing", not "sheeting". If don't believe me, check on the grade stamp of the next panel of sheathing you see.
